Gerbils love to have at least one other gerbil
in their cage with them. You will notice that they tend to
play with each other for long periods during the day. If you
notice that one or both of the gerbils are frequently screaming
they may actually be fighting. In this case it will be necessary
to seperate the gerbils. Sometimes gerbils that are members
of the same family will start to fight. This usually happens
as the baby gerbils mature. When gerbils live in the wild
as soon as the babies mature they are sent off on their own.
If you have an older gerbil and you attempt to introduce
a younger one to the cage it is likely that they will end
up fighting. This is not always the case you can try to put
them together just be sure to monitor their activities closely
over the coming days.
